In 2015, Noah Strycker set himself a lofty goal: to become the first person to see half the world’s birds in one year. For 365 days, with a backpack, binoculars and a series of one-way tickets, he traveled across 41 countries and all seven continents, eventually spotting 6,042 species --- by far the biggest birding year on record. This is no travelogue or glorified checklist. Noah ventures deep into a world of blood-sucking leeches, chronic sleep deprivation, airline snafus, breakdowns, mudslides, floods, war zones, ecologic devastation, conservation triumphs, common and iconic species, and scores of passionate bird lovers around the globe.
